Prolactin levels may be ordered when a person has symptoms of a prolactinoma, such as unexplained headaches, visual impairment, and/or galactorrhea (inappropriate lactation). Testing may be ordered, along with other tests, when a woman is experiencing infertility or irregular menses or when a man has symptoms such as decreased libido, galactorrhea, or infertility. Prolactin levels are also often ordered in men as a follow-up to a low testosterone level.
